gearing Vfor the cutter chain, which at times is ohliged to withstand a very heavy load, is nounted in the firmest and moet substantial fashion. The sprocket wheel driving shaft d has a lower journal in the huh or bracket a2 formed at the rear end of the hed plate a, there being provided for said hearing a reincu'ahley lining on and a step hearing o, An elongated upper journal hearing for the said shaft is provided by the portion C? on the :nain frame, the same also having the removable lining c. By the provision of the hearing.A both above and below the sprocket wheel and above and below the driving gear d" the shaft is maintained in a firm and accurate, alinement. The Counter-shaft E is also provided with an upper journaled hearing at C? und a lower journal hearing at 010, these hearings heilig formed within the main frame (l and Athe removable cap piece C' (Fig. l) the uppr end of which is bolted to the main frame and the lower end held against di ieernent by `the set Screw zf. The lower und of the countenshaft ll rests upon a removable step hearingI piece @2. supported direetly upon a part of the cutter har B. This construction not onlj,lv gives Solidity to the traneinission gearing for the cutting mechanism hut the loeation of the parts gives an extremely ooinpaot forxnation to the machine, permitting it to he shortened to substantially he length taken up by the engine parts alone.

For the reversal of the engine when de- `aired and to avoid the necessity of the usual eccentric and eccentric connections, there is provided a Separate valve crank shaft which has operative connections at opposite ends with the valve .rode 'o' through the cranks and connecting rods` of". Thil,l :shaft is driven from the drivingr pinion g* on the main crank shaft and the. internieshing gear 'of'. the latter upon the internwdiate Shaft ya. Driving' movement is transmitted to the valve Shaft through the driving:r gear g7 loosely mounted on the valve Shaft and adapted to turnthe saine through a suitable clutching' device. For this por pose (Fig. 2l the, gear ie provided witl a` with either lug` of" or 51" (Figs.

y lVhile other methods of feeding or causing travel of the machine during the cutting operation, `or at other rimes. may he einloved, l have herein :shown the feed Chain l, the leading end /i ol which passes about a suitably positioned idle wheel or sprocket wheel it at the eide hut near the forward enfd' of the n'iaehine, thenre rearwarrlhVY ahoiit/ made to travel under its own power either' B v suitablyv positioning the longitudinally or laterally. and either for..

the cutting operation or for positioning the same about the mine floor.

'lo move the niaehlne about the lloor for iositionin iur' oses it is irelerahle to eniploy a higher speed than is employed while' the inarfhine is performing` the cutting operation and the sprocket wheel k therefore may he driven at either one of two Speeds. Referring more iuirtieularlvto Figs. l, 5

and ML tho feed' transmission gearing 'is driven priniarilf,Y from an upright feed drivingv shaft 1* having;f a lower step hearingr /s 1n the iranio (l. and an upper .iournal hearing, in an over head plate which extends" between the engine evlinders, Movement is trai'isniittod from the crank shaft to the shalt (Figs. 1.l 2 and il through atrain of' gearing comprising the bevel gear il?, keyed to the Shaft and meshing with the hereled, pinion if', the latter rotated hy the spur gear Z1". The spur gear 'r inealu-s di rertly with the counter-Shaft 'gear leferriug more particularly to Fig. l() not inlended to he eonstruetioruilly7 arcurzitel drivingV movement Vis transmitted to the sproeket Vwheel if through the train of fearing aa follows: the shaft r; carries` thereon the pinion Zr driven through an overhead vieidahle transniission devil-e here# ina'fier described. The pinion f' meshes with an adjacent gear Z, lieved to the upright high speed driving shaft Z so that the l instantly rotated.

and of the Shaft ,7' to rotaie therewith a aliflia iuteh or nieniher Z 'havingr a lootiuvl l( fare which may he depresed io cimeli u h and drive the pinion Z3. the iziler a toothed upper face. When Splinod to the y thus clutched, the pinion Z3 drives directly moved, the pinion k1 repli.

the main v"sprocketwheel-.driving-gear kf which is keyed fast to the extended sleeve gear La has secured to it the smaller overhead pinion k1", which mesheswith the small idle pinion k, the latter driving the larger' gear m., which is loosely journaled on the upright slow speed driving shaft m. The gear m, which is thus constantlydriven at a reduced rate of speed, may be clutched to drive the shaft m by depression of the sliding clutch member m?, the latter, on depression, havingtoothed engagement 'with the upper face of the gear hub. When thus clutched, the shaft m drives the pinion mi which is keyed thereto, and the pinion meshing with the sprocket driving shaft 7c, drives the sprocket wheel' h3 at a relatively slow rate of speed. In other words', with the clutch -member Z2 raised and the clutch member m2 lowered, the sprocket wheel is driven at the slow or cutting speed. lVith the clutched member Z2 depressed and the clutch member m? raised the sprocket wheel is then driven at its higher or positioning speed.

To obtain speed reductions at the slow speed the gear plate or f if. may he reed h v another and the pinion Zr adjusted to a fresh position. For this purpose the pinion In is carried upon a clamping stud adjustably clamped in an arc-shaped slot 1 in the frame K (see Fig. i2) and pinion icl having merely an interlocking engagement with the gear Zag, may be readily withdrawn on removal of the gear plate.

For engaging cr discngaging the clutch members at will there is provided the sliding controller rod n (Fig. ll) having suitabl;r formed cam grooves n' in its face, which grooves are caused to engage lugs In? and n3, respectively, carried by the sliding clutch members Z2 and m?. The lugs n2 and n3 are formed respectively upon sleeves n? and nf" (Figs. l2 and 13) and these sleeves are retained (Fig. 10) each upon a reduced portion of its respective clutch member by flanged threaded caps n, nl. The formation of the cam grooves is such that when the rod is moved to the right, as'shown in Fig. 10, the clutch member m2 is depressed and the clutch member Z2 raised giving the slow cutting speed. When moved to the left a reverse condition follows giving the high speed. The rod vn slides in guide-ways K vformed in the top of the plate K and is moved in one direction or the other, by' the hand lever as (Fig. pivcted to the plate and having its end engaging a notched portion n? in the t-opv of the rod.

To prevent excessive strain upon the feed-A ing chain during cutting rthere is interposed (Figs Q, 4 andl) between the upright driv- -ing shaft and the sprocket wheel a yield#` Ysaid spring being regulated by an. adjusting nut o3, which may be set to the degree of compression required for transmitting the desired load. Y

In moving the machine about at the higher speed in order to avoid slippage at the transmission device there is provided means for placing pressure upon the transmission device in addition to that of the spring.

For this purpose there is threaded f on the upper end of the driving member 0' f a nut o4 which retains a. washer o5, between which and an underlying shoulder on the driving member there is formed a groove recess into which enters a pair of diametrically opposite pins o carried by the swiveled ring frame o7 (Fig. '2), the latter being pivoted at o8 upon the machine. The opposite end of the ring frame, or that lying on the other side of the transmission member, has a forked portion o9 (Fig. It) carrying the two upright adjusting screws ol0 between which works the cani 0,-'the latter carried'b)Y the cam shaft 012. By turning the hand lever o at the end of the cam shaft the cam o may be turned to raise or lower the ring traine and therefrre detract from or add to the pressure alrea exerted by the spring 0:. Bv merely depressing the ring frame through the handle o13 the transmission del vice ma)T be made to transmit more than the vnormally assigned load and thus avoid slippage at the high speed.

In order to prevent pressure in addition to that of the spring from being placed upon the transmission device during the cutting speed, the cam shaft 012 (Fig. 10`) may be provided with a lug 014, which in the low speed position of the slide rod n is caused to underlie an overhanging lug o carried by said rod. This prevents movement of the cam shaft in a direction to increase the pressure on the transmission slow cutting ,speed.
